When i went to a interview the interviewer ask me a
question for that i cant able to answer him if anyone knows
answer me
How will you design a capacitor bank for a plant? if my p.f
is 0.6 i have to improve it to 0.9 or 1 what kind of steps i
have to do? and is there any formula for calculating this?

Answer Posted / arvind

yes there is an answer fir that, the answer is

KVAR=KW(inv(tan(PF2)-(inv(tan(PF1)))
where tana is desired power factor and tanb is your current
pf.
now to calaulate your a and b parameter we use this formula
power factor =cosa and power factor=cosb
i.e., inv(cos)=power factor
put this in above equation uyou will get your KVAR RATING
but you should the KW of the load.
